Store values in ScriptPanel data object

[toxonic]

@ulrik Oh, this is driving me nuts! I created a snippet, that basically does, what happens in my project file in regard of saving and recalling "presets" (don't mind about that term, i don't mean hise presets). And what shall I say, the example works without issues, also as compiled plugin!
Here's the snippet, but that's kinda senseless to dig into, because this one works...

I'm afraid, I have to find out, where the difference to my project is...

[toxonic]

But it seems not to be a problem, that i can't write to the files, rather than theres something wrong with the internal dummy arrays, that don't seem to work properly.
Whenever i change a preset in the DAW plugin, it shows only default values, but it should at least show the values, that are stored in it's dummy array.
I just copied the preset files from my hise project to the AppData User Presets directory, and as soon, as i change a parameter, the corresponding preset file will be overwritten with null.
Any ideas?

[ulrik]

@toxonic It works here, in Hise no problems.
I compiled it and opened it in Logic, at the first launch, I had not copied the presetFile to the AppData UserPresets folder so it created a new presetFile with all values at undefined.

But if I changed the knob values it wrote them down to the file

[toxonic]

@ulrik Yeah, that's what i mean, the snippet works like expected, but in my project i go pretty much the same way, but it wont work as compiled plugin! That's driving me crazy!

[ulrik]

@toxonic Have you located where on your computer the file "presetFile" is located when you open the daw?
If so, while you're running the daw, open the file with some text editor and have it open, chose a preset and start changing your knobs, is the file changing, what is written inside?

Like this:

[toxonic]

@ulrik Yeah, it's getting overwritten with 'null' , as i stated 2 posts above ... this is, why i believe, it must have something to do with the dummy arrays, but i can't get my head around,why it works in HISE but not with the compiled plugin

[toxonic]

Just to demonstrate my issue, i added a panel, whcih i use to visualize the content of one of the preset dummy arrays.
This is, what it looks in HISE, i can see the values changing, when tweaking parameters:

And this is, what it looks in Ardour as compiled plugin.
Remember, the snippet i posted, which works pretty much the same way, works in both, Hise and in Ardour as compiled plugin....

@toxonic Ok starting from the bottom up then(you have probably done all this):

1. How are you saving these values? In a json file? - I assume yes.
2. In which folder are you saving the file? - I assume AppData
3. How are you loading this data on init?

[toxonic]

@Lindon Thanks for your reply!

1. No, i'm saving the data inside the files via the File.writeObject(ArrayToStore)in a file called for example stutterPresets. The array to store in the files, containing the values for the UI controls is called the same.
2. Yes, actually in AppData/User Presets
3. I made two functions, one to save the arrays in a file and one to recall them.

// Directory to store Presets
var PresetDir = FileSystem.getFolder(FileSystem.UserPresets);

//function store
inline function writePreset (FILE, ARRAY)
{
    local PresetFile = PresetDir.getChildFile(FILE);
    PresetFile.writeObject(ARRAY);
}

//function recall
inline function recallPresets (FILE)
{
	local PresetFile = PresetDir.getChildFile(FILE);
	return PresetFile.loadAsObject();
}

I recall them on init lie this (for example):

stutterPresets = recallPresets("stutterPresets");

PS: What you are seeing in the Panel in my last post are the values of the array, which I wan't to store inside a file. Since this is already empty in the compiled plugin, I don't wonder about, that the files are overwritten with null. I just can't get my head around, why the arrays won't get filled with the parameter values i set in the corresponding "presets"...

@toxonic

Okay so theres no validation going on, and some maybe incorrect naming, and an incorrect call to writeObject: so start like this:

//function store
inline function writePreset (fileName, myJSONData)
{
    local PresetFile = PresetDir.getChildFile(fileName);
    if (PresetFile.isFile())
   {
         PresetFile.writeObject(myJSONData);
   }else{
       // display an error here.....
   };
}

So the most obvious problem is you were trying to save an array when the command expects JSON, so you should fix that at least...
